' NOZZLE FOR LOCOMOTIVES. I

Patented June 19, 1906.

To all whom it mag concern: 1

Be it known that I, HANS OTTO OLSON, a citizen of the United States, residing at Two Harbors, in the county of Lake and State of Minnesota, have invented certain new and useful Improvements in Variable Exhaust- Nozzles for Locomotives, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in variable exhaust-nozzles for locomotives; and it consists of the improved features of construction andcombination hereinafter described and claimed.

In the accompanying drawings, forming part of this speclfication, Figure '1 is a top view of my improved nozzle. Fig. 2 is a cross-section on the line a B, Fig. 1. Fig. 3

is a side elevation of the upper portion of the nozzle, showing the manner in which the adjustable wings are operated; and Fig. 4 is a perspective view ofone of the wings. Fig. 5 is; a perspective view of a modified form of g he exhaust-pipefrom the cylinders of the locomotive may .be of any suitable construction desired, to which is fitted my improved nozzle 1, which I prefer to make of a shape substantially as shown. In the upper portion of the two opposite side walls of the nozzle 1 are recesses 12, in which are journaled the adjustable wings 2 2, which are'formed integral with the operating-shafts, as shown in Fig. 4. The backs of the wings 2 2 are formed-with a fiat surface when larger than the diameter of their journals, while their inner faces are of a taperin concave construction to as nearly as possib e coincide with the inner form of the nozzle, their extreme upper and inner edges being an arc of the circle which forms the discharge-opening of the nozzle. Thus it will be seen that when the wings are brought forward to a choked position the discharge of the nozzle will be practically a circle, whichis the most desirable form possible for the best results.

The wings 2 are provided with the caps 3, which are securely fastened to them for the purpose of covering the opening and reventing the collection of dirt or cinders etween the side wallsof the nozzle and the backs of the wings when the latter are moved forward.

The outside ends 4 and 5 of the wing-shafts are preferably of a square form for the rece tion of the crank- arms 6, 7, and 8, and in t e drawings one is shown as of an indefinite length, as it is designed to roject out through the smoke-box of the ocomotive,

and the crank-arm 8 is attached to it outside of the smoke-box, to which arm in turn may be attached any suitable operating device in common use. The crank- arms 6 and 7 are securely fastened to the shafts 4 and 5 and at theirinner ends are connected by means of the pin 9 in the one engaging within a slotted hole in the other, so that the motion will be applied to the two shafts simultaneously, and

.thus the wings made to openin unison.

For the purpose of inserting or removing the wings 2 2 the portions 10 10 of one of the sidewalls of the nozzle 1 are made removable and are retained. in position by means of the bolts 11 11.

While I have shown the operating- levers 6 and 7 as being located close to the nozzle 1, it is'evident that the shaft 5 may be extended equally as long as the shaft 4 and all of the operating-levers be located outside of the smoke-box, if considered anyadvantage, without departing from my invention.

. The particular advantage in this form of construction is, first, the small proportion of discharge-opening disturbed for the purpose of varying the exhaust, as it isfound in practies that the least the general shape of nozzle is changed the better; secondly, that forming the wing and shaft in one and hinging the wing from its lower edge provides a much .more simple construction than heretofore used and also admits of varying the exhaust by changing the general shape of the interior,

of the nozzle as little as possible, the wings being quite short in proportion to the length of the nozzle. o

In the modification shown in. Fig. 5 of the drawings instead of providing the shaft 12 with the wing 2 I make the same perfectly, round and provide it with the cut-away por-' tion 13, so positioned in the nozzle that when said cut-away portion is in an inward position the walls thereof are unobstructed, but

2. A nozzle comprising a casing having recesses in the opposite mner faces thereof, wings pivotally mounted within said recesses and having concaved inner faces, and caps secured to the upper ends of said wings and having concaved inner edges to correspond with concaved faces of the wings.

3. A nozzle comprising a casing, having recesses in the opposite inner faces thereof, wings pivotally mounted within the said recesses and having their opposite ends flush with the upper end of the casing, and caps secured to the upper ends of said wings and eX- tending over the upper end of the casing.

4. A nozzle, comprising a casing having recesses in the opposite inner faces thereof, wings pivotally mounted within the said recesses and having their upper ends flush with the upper end of the casing, and caps secured to the upper ends of said wings and extending over the upper end of the casing, and having concaved inner ed es to correspond with the concaved faces of the wings.

5. A nozzle, comprising a casing, having a round central bore through the same, the outer and inner faces of said bore having oppositely-arranged recesses, wings pivotally mounted within the lower end of said recesses, and extending up flush with the upper end of the casing, caps carried by said wings and closing said recesses, the pivots of said wings extending through the casing at one side, links rigidly connected to said pivots and pivota-lly connected together, a lever for operating one of said pivots whereby both pivots are operated and both wings are swung inward or outward, thus increasing or decreasing the size of the opening of the nozzle.

6. A nozzle, comprising a casing having recesses in the inner face thereof, wings or shafts pivotally mounted within the inner ends of said recesses and having concaved in- 1 ner faces, and curved caps removably carried by the upper free ends of the wings on the outside of the casing and closing the upper end of said recesses.

7. A nozzle, comprising a casing having recesses in the opposite inner faces thereof, shafts mounted within the inner ends of said recesses and of a diameter greater than the depth of the recesses and having a curved cut-away portion corresponding to that of the inner face of the casing, and means for oscillating said shafts together.

8. A nozzle, comprising a casing having recesses in the opposite inner faces thereof, shafts mounted within the inner end of the said recesses and having upwardly-extending wings, caps removably supported by the u per ends of said wings, and removable blocfrs carried by one side of the casing above the shafts, whereby the shafts and wings may be readily removed.

9. A nozzle, comprising a casing, and shafts mounted in said casing and having curved cut-away portions corresponding to that of the inner face of the casing.

10. A nozzle, comprising a casing, and. shafts mounted in the casing extending longitudinally across the casing and having curved cut-away portions corresponding to that of the inner face of the casing.

11. A nozzle, comprising a casing having semicircular recesses in the opposite inner faces thereof, and shafts mounted within the said recesses and having a curved cut-away ortion corresponding to that of the inner face of the casing.

In testimony whereof I affix my signature in presence of two witnesses.
